NRF24L01+ Misses Packet

[Joseph1]

Guys I made a wireless link using two NRF24L01+ & two MCU units.I want to toggle the reciever side LED bulb when the transmitter side switch presses.

*NRF24L01+ (Black colour Modules) *SPI Data Rate 250Kbps *NRF Air Data Rate 250Kbps *Auto Ack OFF *4 Byte payload *10uF cap on power rails

The problem is the reciever misses many packets even in 10 feet range.Even when I cross my hand it won't send data.

Will the auto acknowledge will improve my problem?

Hi thanks for the comments.The modules I use doesn't have external antenna.It has a pcb antenna.I'll enable auto ACK feature and let ypu all know.
